Description

Technical Field

[0001] The utility model relates to the field of the detection structure design of the fuse tube of an aging board, in particular to a detection device for the fuse tube of an aging test board. Background Technique

[0002] At present, the existing detection method for the fuse tube of an aging test board is mainly to manually use a multimeter for detection. This detection method requires manual measurement of each fuse tube on the aging test board one by one, which takes a long time, and the detector is prone to fatigue, the fingers of the detector are prone to blisters, and it is very inconvenient to record the detection results, and it is easy to make mistakes, which will cause the test socket to be open circuit due to recording errors during the test, affecting the test results.

[0003] Therefore, a detection device for the fuse tube of an aging test board is provided. This device can automatically detect the fuse tube. The system records the position of the fuse tube on the aging test board and whether there is an abnormal state of the fuse tube at the corresponding position, which is convenient for the staff to quickly find the fuse tube with an abnormal state and perform maintenance on it in time. The detection efficiency is relatively high, and it can greatly reduce the burden of manual detection. Content of the Utility Model

[0004] The purpose of the utility model is to provide a detection device for the fuse tube of an aging test board, which solves the problems put forward in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A detection device for the fuse tube of an aging test board, including a carrier frame, the number of the carrier frames is two, the two carrier frames are symmetrically arranged, a notch is opened at the inner side of the top of the carrier frame and a conveyor belt is installed in the notch, the tops of the two conveyor belts carry an aging test board, a plurality of uniformly distributed test sockets are fixed on the top of the aging test board, and fuse tubes are connected to both side walls of the test socket;

[0006] A gantry is fixedly installed across the tops of the two carrier frames, an electric push rod is fixed at the middle of the top of the gantry, the push rod of the electric push rod movably penetrates through the gantry and is fixedly connected with a lifting plate, and a plurality of uniformly distributed pressing jigs are fixed at the bottom of the lifting plate.

[0007] By adopting the above technical solution, the conveyor belt is a transportation mechanism for transporting the aging test board. The conveyor belt transports the aging test board to the detection position and moves the aging test board according to the point position setting of the conveyor belt. Then, the electric push rod is used to drive the lifting plate to descend, so as to use the pressing jig to detect the fuse tubes on both sides of each row of test sockets. Then, the conveyor belt transports the aging test board that has been detected to the unloading end for the staff to perform the unloading operation.

[0008] As a preferred embodiment of the present utility model, a connecting plate is fixed to one side of the bottom of the cross beam of the gantry. A code scanning camera is fixed to the end of the connecting plate, and a two-dimensional code is fixed at a corner of the top of the aging test board.

[0009] By adopting the above technical solution, when the conveyor belt transports the aging test board to the lower end of the pressing fixture, the code scanning camera on the gantry will first scan and read the two-dimensional code in the upper left corner of the aging test board. The content of the two-dimensional code is the aging test board number. After the successful code scanning and reading, the aging test board number will be entered into the system.

[0010] As a preferred embodiment of the present utility model, the pressing fixture includes a pressing block and probe heads. The pressing block is fixed to the bottom of the lifting plate, and probe heads are fixed at the four corners of the bottom of the pressing block.

[0011] By adopting the above technical solution, during the detection, the pressing fixture moves downward. The pressing block at the lower end of the pressing fixture will extend into the test seat but not touch the test seat. As the pressing fixture continues to move downward, the probe heads at the lower end of the pressing fixture will contact both sides of the fuse tubes at the front and rear ends of the test seat. The vertical downward movement of the above pressing fixture is a movement at a set point, so there is no risk of accidental touch. After the probe heads of the pressing fixture contact both sides of the fuse tubes, power will be applied to detect whether the fuse tubes are abnormal at a low voltage. After the detection is completed, the detection results and the positions of the corresponding fuse tubes on the aging test board will be entered into the system together. Subsequently, the pressing fixture moves vertically upward, away from the fuse tubes of the first row of test seats on the aging test board.

[0012] After the pressing fixture moves away from the fuse tubes of the first row on the aging test board, the conveyor belt will move the aging test board in a point position along the unloading end direction, place the fuse tubes of the test seats in the second row of the aging test board at the lower end of the pressing fixture for detection, and repeat the above movement until all the fuse tubes on the entire board of the aging test board are detected. Subsequently, the conveyor belt transports the detected aging test board to the unloading end for the staff to perform the unloading operation.

[0013] As a preferred embodiment of the present utility model, the distance between the vertical side walls of the two notches is greater than the width of the aging test board.

[0014] By adopting the above technical solution, it is possible to avoid friction between the aging test board and the inner wall of the notch when the conveyor belt drives the aging test board to move.

[0015] As a preferred embodiment of the present utility model, limit rods are fixed to both sides of the top of the lifting plate, and the limit rods movably penetrate through the gantry.

[0016] By adopting the above technical solution, the setting of the limit rods enables the lifting trajectory of the lifting plate to be limited, ensuring stable lifting.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] Through the automatic feeding operation mechanism of the conveyor belt, the present utility model can automatically detect each row of fuses on the aging test board, avoiding the problem of low detection efficiency caused by manual handling and manual detection, and greatly improving the detection efficiency. Regarding the QR code set at the upper left corner of the aging test board and the detection results entered into the system each time the pressing fixture detects a fuse and the function of the Dut position corresponding to the detection results, it is very helpful for the staff to quickly find the fuses in abnormal states and perform timely maintenance.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0029] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0030] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "set" should be understood in a broad sense. For example, it can be fixedly connected and set, or detachably connected and set, or integrally connected and set. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The models of the electrical appliances provided in the present utility model are only for reference, and different models of electrical appliances with the same function can be replaced according to actual usage conditions.

[0031] Please refer to Figures 1-4 , the present utility model provides a technical solution: a detection device for a fuse tube of an aging test board, including a carrier 1. The number of carriers 1 is two, and the two carriers 1 are symmetrically arranged. A notch is provided on the inner side of the top of the carrier 1, and a conveyor belt 11 is installed in the notch. The top of the two conveyor belts 11 carries an aging test board 2. A plurality of uniformly distributed test seats 21 are fixed on the top of the aging test board 2, and fuse tubes 23 are connected to both side walls of the test seats 21;

[0032] A gantry 3 is fixedly installed across the top of the two carriers 1. An electric push rod 33 is fixed at the middle of the top of the gantry 3. The push rod of the electric push rod 33 movably penetrates through the gantry 3 and is fixedly connected to a lifting plate 31. A plurality of uniformly distributed pressing jigs 32 are fixed to the bottom of the lifting plate 31;

[0033] Among them, the conveyor belt 11 is a transportation mechanism for transporting the aging test board 2. The conveyor belt 11 transports the aging test board 2 to the detection position, and the conveyor belt moves the aging test board 2 according to the point position setting. Then, the electric push rod 33 is used to drive the lifting plate 31 to descend, so as to detect the fuse tubes 23 on both sides of each row of test seats 21 by using the pressing jigs 32. Then, the conveyor belt 11 transports the aging test board 2 that has been detected to the unloading end for the staff to perform the unloading operation.

[0034] Furthermore, limit rods 34 are fixed to both sides of the top of the lifting plate 31. The limit rods 34 movably penetrate through the gantry 3. The arrangement of the limit rods 34 enables the lifting trajectory of the lifting plate 31 to be limited, ensuring stable lifting.

[0035] Further, the distance between the vertical side walls of the two notches is greater than the width of the aging test board 2, so as to avoid friction between the aging test board 2 and the inner wall of the notch when the conveyor belt 11 drives the aging test board 2 to move.

[0036] As Figure 1 and 3 shown; one side of the bottom of the cross beam of the gantry 3 is fixed with a connecting plate 35, the tail end of the connecting plate 35 is fixed with a code scanning camera 36, and a two-dimensional code 22 is fixed at a corner of the top of the aging test board 2;

[0037] When the conveyor belt 11 transports the aging test board 2 to the lower end of the pressing fixture 32, the code scanning camera 36 on the gantry 3 will first scan and read the two-dimensional code 22 in the upper left corner of the aging test board 2. The content of the two-dimensional code 22 is the number of the aging test board 2. After the successful code scanning and reading, the number of the aging test board 2 will be entered into the system.

[0038] As Figure 1 and 2 shown in Figures 3 and 4; the pressing fixture 32 includes a pressing block and a probe head. The pressing block is fixed at the bottom of the lifting plate 31, and probe heads are fixed at the four corners of the bottom of the pressing block;

[0039] During the detection, the pressing fixture 32 moves downward. The pressing block at the lower end of the pressing fixture 32 will extend into the test socket 21 but will not touch the test socket 21. As the pressing fixture 32 continues to move downward, the probe heads at the lower end of the pressing fixture 32 will contact both sides of the fuse tube 23 at the front and rear ends of the test socket 21. The vertical downward movement of the above-mentioned pressing fixture 32 is a movement at a set point, so there is no risk of mis-touching. After the probe heads of the pressing fixture 32 contact both sides of the fuse tube 23, the fuse tube 23 will be detected for abnormality by applying a low voltage. After the detection is completed, the detection result and the position of the corresponding fuse tube 23 on the aging test board 2 will be entered into the system together. Then the pressing fixture 32 moves vertically upward, away from the fuse tube 23 of the first row of test sockets on the aging test board 2.

[0040] After the pressing fixture 32 moves away from the fuse tube 23 of the first row on the aging test board 2, the conveyor belt 11 will move the aging test board 2 in a point-by-point manner along the unloading end direction, place the fuse tube 23 of the test socket 21 in the second row of the aging test board 2 at the lower end of the pressing fixture 32 for detection, and repeat the above movement until all the fuse tubes 23 on the entire board of the aging test board 2 are detected. Then the conveyor belt 11 transports the detected aging test board 2 to the unloading end for the staff to perform the unloading operation.

[0041] The implementation principle of a detection device for the fuse of an aging test board in this application is as follows: Place the aging test board 2 on the top of the conveyor belts 11 on both sides. The conveyor belts 11 transport the aging test board to the detection position. When the conveyor belts 11 transport the aging test board 2 to the lower end of the pressing fixture 32, the code scanning camera 36 on the gantry 3 will first scan and read the two-dimensional code 22 in the upper left corner of the aging test board 2. The content of the two-dimensional code 22 is the number of the aging test board 2. After the successful scanning and reading, the number of the aging test board 2 is entered into the system. The pressing fixture 32 moves downward, and the pressing block at the lower end of the pressing fixture 32 extends into the test socket 21 but does not touch the test socket 21. As the pressing fixture 32 continues to move downward, the probe heads at the lower end of the pressing fixture 32 will contact both sides of the fuse 23 at the front and rear ends of the test socket 21. The vertical downward movement of the above-mentioned pressing fixture 32 is a movement at a set point, so there is no risk of accidental touch. After the probe heads of the pressing fixture 32 contact both sides of the fuse 23, power is supplied to detect whether the fuse 23 is abnormal at a low voltage. After the detection is completed, the detection result and the position of the corresponding fuse 23 on the aging test board 2 are entered into the system together. Subsequently, the pressing fixture 32 moves vertically upward, away from the fuse 23 of the first-row test socket of the aging test board 2. After the pressing fixture 32 moves away from the fuse 23 of the first row of the aging test board 2, the conveyor belts 11 will move the aging test board 2 in a point-by-point manner along the direction of the unloading end, placing the fuse 23 of the test socket 21 in the second row of the aging test board 2 at the lower end of the pressing fixture 32 for detection. Repeat the above movement until all the fuses 23 on the entire board of the aging test board 2 are completely detected. Subsequently, the conveyor belts 11 transport the detected aging test board 2 to the unloading end for the staff to perform the unloading operation.
